Abstract :
Technological developments in the aerospace sector are currently very
rapid. The engine is an important part of operating an airplane. The positioning of
an engine can affect the aerodynamic performance of the airplane. The use of a
Target Drone with an Electric Duct Fan (EDF) engine is used for auxiliary
purposes in military shooting practice, so an analysis of the choice of engine
position on the Blitzer A23 Drone Target is needed to get a good L/D value.
Therefore, it is necessary to study the propulsion configuration regarding the
aerodynamics and effectiveness of the control plane on the Blitzer A23 Drone
Target. The method used is the Numerical Method/CFD (Computational Fluid
Dynamic). Testing of the 3-dimensional Target Drone model that had been
designed was carried out in cruising conditions. Apart from that, the tests also
carried out variations in the engine position configuration, namely on the fuselage,
wing and inside the fuselage. It can be seen that the effect of the engine position
configuration on aerodynamics and the effectiveness of the control plane which has
the best value is the position of the engine in the fuselage. From the aerodynamic
analysis that has been carried out to obtain the aerodynamic characteristics of the
BLITZER A23 Drone Target, namely the configuration of the engine position on the
fuselage, the lift value is 878,914 N and the drag value is 103,518 N. Then for the
engine position configuration on the wing, the lift value is 999,267 N and the drag
value is obtained. amounting to 97,463 N. Furthermore, for the configuration of the
engine position in the fuselage, the lift value was 1539,48 N and the drag value was
111,114 N. From the three analysis results, the propulsion configuration used was
the engine position configuration in the fuselage because it had an L/D value the
best.
